This app is absolutely free and helps to prepare effectively and productively for the Einbürgerungstest needed to become a German citizen. The app offers different learning modes such as a test, an exam, questions by topics and includes all official 300 questions + 10 questions per selected state. The questions are asked in a random order every time, no matter if 10, 20, 33 or all questions are selected. The answers can also be shuffled via settings and thus sorted differently for each run.
